This is a good question. You will probably need to set the capital slider to zero and wait until all trades are closed before starting the new system. But I'll check with the developers to be sure.
Update: Yes, let the trades close. You can start a new session in parallel when you install the new Zorro version in a different folder. Otherwise wait until all trades are closed, then install the new version and start the session.
